Hi,
I think you are referring to the r-squared value of an equation that models a set of data. Often times when we plot a set of data, we want to find a relationship between the points that reveals an underlying relationship. In some cases, that relationship is linear, that is all the points lie roughly on a line.
The R-squared value tells you how well your line fits the points that you've plotted. It's simply a way of judging how good your approximation is.

R?
I have no idea what you are talking about
All I know is thats an equation for a straight line.
You plug everything in. M is your slope, and B is your Y intercept.
I think..haha

[(b)^2 + (b/m)^2]^(1/2)

I don't see an 'R' anywhere in that equation.
